CLEVIS.

SPECIFICATION forming part of Letters Patent No. 602,022, dated April 5,1898. Application filed Decemberl9,1896. Serial No. 616,330. mailman.)

To aZZwhom it may concern.-

Be it known that I, WILLIAM H. LIGHTCAP, a citizen of the United States,residing at Hazel Green, in the county of Grant and State of Wisconsin,have invented a certain new and useful Improvement in Olevises,of whichthe following is a specification, such as will enable others skilled inthe art to which it appertains to make and use the same.

The object of my invention is to form a clevis of a simple and cheapform of construction so made that the same cannot be accidentallydisplaced or separated from the doubletree; and to this end my inventionconsists of an upper and lower bar joined together at one end by astraight pin and at the other by a curved link for the attachment of thesingletree, the pin and link being provided at the ends with suitablelugs adapted to register with suitable slots adjacent to the holes inthe straight piece when in one position and to be out of registrytherewith when the parts are in the working position, although it is notto be understood that such invention is limited to such exact form ofconstruction, for my invention consists in the construction of certaindevices and parts and the combination of certain devices and parts, allas hereinafter more specifically described, set forth, and claimed.

The device of this invention is set forth in the followingspecification, of which the accompanying drawings form 'a part, whereinsimilar letters of reference designate like or equivalent parts whereverfound throughout the several views, and in which Figure 1 is a top planview of my improved clevis in working position. Fig. 2 is a side viewthereof; Fig. 3 is a side View thereof in central-vertical section onthe line 3 3 of Fig. l, the disconnecting position of the parts beingshown in dotted lines; and Fig. t is a top plan view of such clevis inposition upon the doubletree, the position assumed by the same inremoval being shown in dotted lines. I

Fig. 5 is a top plan View of a modified form of the construction shownin Figs. 1 to 4 in the rearward, loosening, or non-working position uponthe doubletree; and Fig. 6 is a side view, partially in central verticalsec- .tion, of the construction shown in Fig. 5, the

shown.

disconnecting position of the parts in said Figs. 5 and 6 being shownindotted lines.

Referring to the drawings, A designates a straight bar forged or castfrom suitable metal or any otherdesiredmaterial, which is provided atone end with a pin or rod B,

which is preferably formed integral therewith or secured firmly theretoat one end, as This pin B is preferably of rounded form throughout and,is provided at the top with a suitable lug C, as shown.

. D designates a bar similar to the bar A and preferably of the sameshape, and this bar D is provided at one end with a hole E, preferablyround as shown, and at the other end with a similar hole F, each ofwhich holes E and F is preferably provided upon the inward side thereofas shown, with suitable slots G and H respectively, and the bar A isprovided at its outer end with a suitable hole K, provided with asimilar' slot I.

L designates a link which may be of any'desired form, but ispreferablyof thatshown, consisting of the curved central portion M, provided atthe ends with the roundedljournal portions N and N, provided at theextreme ends with the lugs O and O, which rounded journal portions andlugs are similar in shape and'form to the rounded upper portion B, andlug O of the pin B and the link L is preferably provided with theshoulders P and P;

Adjacent to the journal holes or perforations E and F, and preferablylocated in the side thereof opposite to the slots H and G, arepreferably provided countersinks Wand Y of the same form and contour andadapted to receive the lugs O and O,and the bar A is preferably providedwith a similar countersink Y torreceive the lug O. Y

R represents the frontof the clevjs and S the back thereof, while Qdesignates the doubletree and U the whiffietree.

If desired, the pin B, instead of being formed integral with or securedto the bar A at the bottom, maybe connected therewith in the same manneras it is with the bar D also, instead of having the journal end portionsof the pin B and link L project beyond the bars A and D, suitablecountersinks may be provided of sufficient depth to receive the.

sufficient to permit the clevis to be swung, from front to rear aroundthe end thereof, and the end of the doubletree is preferably of therounded form shown at V in Fig. 2, so that it will be impossible toswing the link L into the non-working or disconnecting position shown indotted lines in Fig. 3 before the clevis has been swung to the extremerearward position shown in dotted lines in Fig. 2. i i The parts beingdisconnected, to assemble the clevis in position upon the doubletree soas to connect the whiffletree therewith the pin B is passed through thehole U in the doubletree, and the bar D is then placed on the end of thepin B by bringing the slot E 3 into registry with the lugO and slippingthe. bar D down over the pin B,when such bar D 1 will assume theposition shown in dotted lines inFig. 3, after which it is swung aroundinto position parallel to and extending over the bar A, when the bar Dwill be of course locked to the pin B, and such bars A and D extending,as they do, to the rear of the doul bletree, as shown in dotted lines inFig.4,

the rounded journal portion N of the link L is inserted in position inthe bar A, with the bowed portion M of the link extending toward the pinB, as shown in dotted lines in Fig. 3, after which the ring or link X ofthe whifi'ietree U is passed over the link L and the bar D passeddownoverthe journal Nof the link, when by the rotation of the link L to thefront or working position, as shown in full lines in Figs. 1 to 4.,inclusive, the various'parts of the clevis will belockedtogether,

andwhen the clevis is-then swung around the end of the whiflietree Binto the position shown in Fig. 4: it will be seen that it will beimpossible when in such working position to rotate the link Lsufficiently far to the rear to permit of the disconnecting of thevarious parts of the clevis;

111 the modified form of construction of my improved clevis shown inFigs. 5 and 6the 'hole in the bar D, through which passes the end of therod or pin B, is made of a rectangular form, andthe upperendof the pinB, instead of being of the rounded form-shown in the preceding views, ismade of a square form and provided with a lip O,preferably of the samewidth as the square head of-such square end portion of the pin. The linkL, instead of having the centers of the end journal or pivot portionsthereof coincident and in line one with the other, has that journal 'orpivot N,w11icl1 passes through the bar D,

located nearerto the bowed-portion M of such link Lthan is the bottompivotN, as shown in Figs. 5 and G, in such manner that the rotation ofthe link L will give a reciprocating motion to the bar D, for the reasonthat being pivoted to the bar A the journal or pivot N, pivoted in thebar D, will act upon such bar as an eccentric. Then it is desired todisconnect this form of the device from the doubletree, the clevis isswung around into the rearward position on the doubletree (shown indotted lines in Figs. 4, 5, and 6) and the link L is then swung into therearward and non-working position shown in dotted lines in Fig. 6. Whenin this position, the bar D will be forced back into the position shownin dotted lines in said Figs. 5 and 6, in which position the lip O ofthe square upper portion of the pin B will register with the slot H, andthe bar D can be disconnected therefrom, swung'to one'side, and the pinB be forced down through the doubletree and the singletree removedtherefrom, and the reconnecting of this formonthe clevis is,of course,the reverse of this process. The advantage of this form of the devicelies in the fact that allthe parts are permanently connected togetherand cannot be separated one from another, as the endsof the link L areriveted down over the bars A and D, so asto allow of sufficient movementthereof for the purpose described, while allowingof free rotationof thelink L, and in either form when loosely connected the link L may beriveted,

as shown in Figs. 5 and'6.

My improved form of clevis shown herein is of such form that it may beusedwith either the bar A-or bar D uppermost, as may bodesired; butordinarily it is preferable to use the same with the bar A at the topand the bar D underneath.

Having now particularly described my said invention, its constructionand operation, what Iclaim, anddesire to secure by Letters Patent, is

1. In a clevis, the combination with a bar A, of-a pin B, a link L, anda bar D, the bar D being provided with holes adjacent 'to the endsprovidedwith the slots IIand G, and the pin and link being provided withsuitable lugs adapted to register with the slots, substantially as shownand described.

2. In a clevis, the combination withabar A having rigidly. securedthereto a pin B having a lug C, a link L having the pivot'or journal endportions N and N provided with like lugs, and a bar D havingsuitable journal-perforations adapted to receive the journal portions of the pin Band link L and provided withsuitable slots H and G to allow of theconnection of the parts when in oneposition, and the bar A beingprovided with asuitable journal-perforation and slot adapted to receivethe pivot portion Not the link L, substantially as shown and describedand forthe purposes set forth.

3. =In-a clevis, the combination with abar A, of a pin B, a bar D, and acurved link L provided with journal portions N and N pivoted in the barsA and D, the construction being such that the bar D can only bedisconnected from the pin B when the bow of the link is pointing towardthe pin B, substantially as shown and described and for the purposes setforth.

4. In a clevis, the combination with a bar A, of a bolt B having a lip Oat the upper end,

a bar D having a slot H, and a link L pivoted to the bars A and D insuch manner as by its rotation to give a reciprocal movement to the barD so as to lock and unlock the same from the pin B, substantially asshown and described and for the purposes set forth.

5. In a clevis, the combination with a bar A, of a bolt B connected atone end with the bar A and having a lip O at the other end, a barwDhaving a slot H adapted to fit over the lip O and be drawn back underthe same, and a curved link L rotatably pivoted in the bars A and D thepivots being eccentric one to another, substantially as shown anddescribed and for the purposes set forth.

Signed, at the city of Hazel Green, Grant county, in the State ofWisconsin, this 7th day of December, A. D. 1896.
